feat(schema): add default field to question tool for pre-filled text inputs

[jeonghun-jj-lee]

Adds an optional default string field to the question schema (both V1 and V2). When set on a kind: "text" question, the UI pre-fills the text input with the value so the user can edit before submitting.

Changes

• Schema (packages/schema/src/question.ts + v1/question.ts): added default?: string to the question base struct
• Tool description (packages/core/src/tool/question.ts): documents the new field for the LLM
• App UI (session-question-dock.tsx): seeds store.custom from question defaults on mount
• TUI (question.tsx): same seeding pattern
• SDK (types.gen.ts): regenerated with default?: string on QuestionInfo

Verification

• Core question tests pass (6/6)
• Full monorepo typecheck passes (30/30 packages)

Motivation

The onboarding interview needs to present an auto-generated user description for confirmation/edit — the user should see it pre-filled and be able to modify before submitting.

📝 Walkthrough

Walkthrough

Question schemas now support optional editable defaults. The question tool preserves these values, and app and TUI session inputs use them when initializing custom answers.

Changes

Question default values

Layer / File(s)	Summary
Question schema and tool propagation packages/schema/src/question.ts, packages/schema/src/v1/question.ts, packages/core/src/tool/question.ts, packages/core/test/tool-question.test.ts	The shared question schemas add an optional default string. The question tool documents and tests forwarding this value for text questions.
Session input initialization packages/app/src/pages/session/composer/session-question-dock.tsx, packages/tui/src/routes/session/question.tsx	Custom-answer state initializes from each question’s default value and falls back to an empty string.
